Description
Technical field
The utility model relates to a kind of staircase main drive, belongs to the drive element class of escalator.
Background technology
At present, the actuating device of escalator step generally includes main drive sprocket and formations such as step drive sprocket and bearing seat, and main drive sprocket wherein, its thickness generally reach 20mm; Step drive sprocket wherein, its thickness are 16.5mm.Their processing need be adopted the thick and thick steel plate of 22mm of 20mm to carry out car system respectively and form, form with regard to need adopting steel plate than the own size of sprocket wheel much bigger (thickness) to carry out turning like this, it not only causes a large amount of metallic material of waste, and needs specific Fabricating machinery.
All the time, people are seeking a kind of way that reduces the escalator productive costs, also attempt to improve the structure or the material of escalator and actuating device, can save metallic material as much as possible and save cost, can guarantee simultaneously safe reliability and its quality and rigidity that step drives again, also take into account the steel plate thickness of considering on real level of processing and the market commonly used.
Chinese patent by retrieval, the patent of relevant escalator apparatus aspect has much, and they relate generally to the improvement of escalator body, step, do not relate to the technology appearance identical with the present utility model purpose.
Summary of the invention
The purpose of this utility model is to the in-problem improvement of prior art and fills up, a kind of staircase main drive is provided, be specifically related to the improvement of staircase main drive sprocket and step drive sprocket configuration aspects, make the thickness of step drive sprocket do thinlyyer, and by the bolt between the reinforced rib of setting up some on the main drive sprocket and connection sprocket wheel, realize saving metallic material, save the purpose of cost, can guarantee simultaneously quality and rigidity that step drives again, and when operation is safe and reliable, and can adapt to the processing of conventional equipment and adopt common steel plate (thickness) on the market.
Concrete technology contents of the present utility model is: a kind of staircase main drive is characterized in that: comprise that bearing seat, main drive sprocket, step drive sprocket, handrail drive drive sprocket, main drive shaft; Wherein:
Described bearing seat and step drive sprocket all have two at least,
The reduced thickness of described step drive sprocket is 16mm,
On described main drive sprocket, be provided with spoke and screw.
The utility model compared with prior art has following good effect:
1, owing to, not only saved material, saved cost, can adapt to conventional equipment processing again and adopt steel plate thickness commonly used on the market the reduced thickness of step drive sprocket.
2,, safe reliability and its quality and rigidity that step drives have been guaranteed owing to structural reasonable improvement to main drive sprocket and step drive sprocket.
3, the utility model simple in structure, reasonable in design, draw materials easily, processing and install very conveniently, be desirable failure-free staircase main drive, the particularly main chain gear apparatus part that drives.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the front schematic view of part 2 among Fig. 1;
Fig. 3 is the front schematic view of part 3 among Fig. 1.
Indicate among the figure: 1, bearing seat, 2, main drive sprocket, 3, the step drive sprocket, 4, handrail drives drive sprocket, 5, main drive shaft, 6, screw, 7, spoke, 8, screw.
The specific embodiment
Further describe detailed technology content of the present utility model and embodiment below in conjunction with accompanying drawing.
But please note: mark shown in the drawings and embodiment should not regard that to the utility model technology limitation any expansion and increase on the utility model basis all is considered as protection domain of the present utility model as.
The staircase main drive that the utility model provides, it comprises,
Bearing seat 1, main drive sprocket 2, step drive sprocket 3, handrail drive drive sprocket 4, main drive shaft 5; Wherein: described bearing seat 1 and step drive sprocket 3 all have two at least, and the equal attenuate of the thickness of described step drive sprocket 3 is 16mm, are provided with spoke 7 and screw 6 on described main drive sprocket 2.
Described step drive sprocket 3 generally all adopts the thick steel plate car system of 16mm to form, and can certainly consider to adopt other thickness and other material, as alloy material, has saved cost to a great extent like this when reducing the turning amount.
Spoke 7 set on the described main drive sprocket 2 is generally 4～6, is even layout.
2～4 screws 6 are arranged on described spoke 7, be on the interior circle that is evenly arranged in spoke 7.
Set up 2～4 screws 8 on the inner ring of the step drive sprocket 3 of described main drive sprocket 2 one sides, the number needs of the screw 6 on it and the described spoke 7 will be consistent, and the position is corresponding mutually, is inter-connected via a bolt joint fixing.
The inventor is considering that the step drive sprocket changes the reduction that Bao Houhui causes its rigidity, and especially therefore the step drive sprocket of main drive sprocket side reduces the adverse effect that produces because of the attenuation of step drive sprocket by changing the main drive chain wheel construction.
Accompanying drawing of the present utility model is represented contriver's most preferred embodiment, it is on former main drive sprocket basis as long as increased by six spokes and three screws simply, and correspondingly increase by three screws on the step drive sprocket, main drive sprocket connects the bolt that adopted and has been increased to nine by original six with the step drive sprocket like this, and the bolt that increases is distributed in the middle part of step drive sprocket, thereby has improved its rigidity greatly.
The utility model only is described in detail with regard to a most preferred embodiment of the present utility model; but can not be interpreted as the restriction of other modes that the utility model is implemented; everyly further improve and similar or identical scheme on the utility model basis, all being considered as is the scope that the utility model is asked for protection.
